The A-La-Uno that was launched in December 2006 solved the problem of scale adhesion, which was an issue in hygienic ceramics, by adopting new organic glass on the main body. The principal feature is that it maintains cleanliness and is easy to clean. In June 2014, the new A-La-Uno with enhanced environmental performance as well as improved cleanliness was released.
The eco-conscious features including the quick-warming seat that immediately heats only when the toilet is in use, instantaneous water heater that heats water for washing while it is used, and an ECONAVI function that controls operation and room temperature by sensing the user's presence in the bathroom or on the toilet seat, have achieved the industry's top-class*1 energy-saving performance. A significant amount of water is also saved with the turn trap flushing system which releases accumulated water at once with little water. Compared with toilets of twenty years ago, the A-La-Uno yields total annual savings of roughly 6,000 yen in electricity costs and about 14,000 yen in water costs.
The focus on cleanliness in the design also contributes to environmental performance. In addition to the novel organic glass and the easy-to-clean shape, a triple guard that prevents against scattering, dripping, or leaking has been adopted. This reduces not only the time required for cleaning, but also the amount of cleaning agents and water used.
